Excerpt

Testing WebSocket API Security

When to Use

Assessing real-time communication APIs that use WebSocket (ws://) or Secure WebSocket (wss://) protocols
Testing for Cross-Site WebSocket Hijacking (CSWSH) where an attacker's page connects to a legitimate WebSocket server
Evaluating authentication and authorization enforcement on WebSocket connections and messages
Testing input validation on WebSocket message payloads for injection vulnerabilities
Assessing WebSocket implementations for denial-of-service through message flooding or oversized frames

Do not use without written authorization. WebSocket testing may disrupt real-time services and affect other connected users.
